Thessia

The girl known only as Thessia encountered the scions of the Perseus Dynasty aboard the Righteous Indignation. She quickly gained their trust and led them into an ambush at the hands of Geraldus Finneus THaddeus Minerva Tibalt Merkavian XIV.
Charismatic and possessing an enormous degree of cunning, it is not clear whether she is a loyal follower of Geraldus XIV, or merely a paid mercenary hanger-on.
